I know sometimes people don't have much choice, but I'd move heaven & earth to avoid sending a child to a school that puts on bouncy castles & ice creams (etc) for 100% attendance.
It is punitive to the children who are the ones MOST likely to need support, to feel good about themselves & to get a treat.
Primary aged children have no control over their attendance, to reward or punish them for illness, disability, sn or their parents choices is just awful and I wouldn't trust trust the pastoral care of the school.
It's all very well telling kids what BS it is, but they're still the ones missing out through no fault of their own.
As for the school(s) making it a class thing. Fucking hell. That's diabolical. They should be teaching children to build friendships, to care for each other, to look out for those who have greater needs - not setting them up tomtearveach other apart. This really, really pisses me off and upsets me. No, just no.
Honestly, I love our school, but reading threads like this REALLY makes me appreciate just how great they are.
